C1 Danger Present
A danger is present and immediate action is needed to remove or control the risk.

A clear guide to understanding an unsatisfactory report, prioritising observations and planning electrical remedial work around your premises.

An Electrical Installation Condition Report records the condition of the fixed electrical installation at the time of inspection. If the report is marked unsatisfactory, the observation codes explain where action or further investigation is needed.
The next step is to turn those observations into a sensible scope of work. Urgent risks need prompt attention, while other improvements can be planned around access, budgets and the way the building operates.

From Findings to Action
Each observation should lead to a clear priority, scope and record of the completed work.
Observation codes help the duty holder understand the nature of a finding. The report and the qualified inspector provide the context for deciding the next action.
A danger is present and immediate action is needed to remove or control the risk.
The finding is potentially dangerous and remedial action should be treated as a priority.
Further investigation is needed because the inspector could not confirm the cause or full extent of a concern.
Improvement is recommended, but this code alone does not make the report unsatisfactory.
Each relevant observation should be translated into a practical description of the work, access and expected outcome.
Where immediate danger is not present, work can be coordinated around agreed access and operational requirements.
Choose the service that best matches the equipment, installation or action identified in this guide.
Arrange an inspection of the fixed electrical installation with clear reporting and practical next steps.
Plan alterations and installation work around the needs of an occupied commercial building.
Get support when an electrical fault or urgent finding needs a practical response.

A structured response keeps urgent matters visible and gives the business a clear record from the original finding through to completed work.
Read the overall assessment and every observation code
Follow the inspector’s advice where an immediate danger is present
Confirm whether further investigation is needed before work is priced
Group remedial work by priority, area and access requirement
Agree any isolation or shutdown arrangements before work begins
Keep the report, certificates and confirmation of completed work together
The exact response depends on the report, but the route from findings to reliable records should remain easy to follow.
The report, observation codes and any supporting information are reviewed in context.
Urgent risks, further investigation and planned improvements are separated clearly.
The agreed work is coordinated around safe access and operational requirements.
Relevant certificates and completion records are added to the site safety file.

CTS can review the findings, prepare a clear quotation and coordinate suitable electrical remedial work. Access, isolation and timing are agreed before work starts so the programme reflects how the premises operates.
Not in every case. The response depends on the observations recorded. A C1 finding identifies danger present and needs immediate action. Other findings should be reviewed with the inspector so the correct priorities and controls can be agreed.
A report containing C1, C2 or FI observations is normally assessed as unsatisfactory. A C3 observation recommends improvement but does not make the report unsatisfactory on its own.
Where the safety of the installation allows, work can be planned around agreed access, quieter periods and operational requirements. Immediate dangers still need prompt action.
The paperwork depends on the work completed. It may include an Electrical Installation Certificate, a Minor Electrical Installation Works Certificate or other confirmation linked to the original observations.
The original report remains part of the site record. Relevant certificates and confirmation of completed work should be kept with it to show how the observations were addressed.
